ROLLER-BEARING.

SPECIFICATION forming; part of Letters Patent No. 718,122, dated January 13, 1903.

Application filed June 27, 1902. Serial No. 113,455. (No model.)

To aZZ whom it may concern:

Be it known that LALBERT ENNIS HENDER- SON, of the city of Toronto, in the countyof York and Province of Ontario, Canada, have invented certain new and'useful Improvements in Roller-Bearings; and I hereby declare that the following is a full, clear, andmounted thereon andinterpose spacing-wash ers between the inner faces of the retainingrings and the shoulders of the journals to hold the retaining-rings properlyspaced from each other and from the ends of the bearingrollers and so arranged that they will contact the ends of the spacing-rollers and prevent the longitudinal displacement of the same on the tie-rods. V

In the drawings, Figure 1 is aperspective view of a roller-bearing with one of the bearingrings removed to show the relative position and the construction of the bearing-rollers, tie-rods, and spacing-rollers. Fig. 2 is a perspective view of one of the bearing-rings. Fig. 3 is a sectional view of one of the spacing-rollers, tie-rods, and a portion of each of the bearing-rings. Figs. 4 and 5 are similar views of modifications shown in Fig. 3.

Like letters of reference refer to like parts throughout the specification and drawings.

For an understanding of the present invention I have shown it applied to a specific form of roller-bearing; but I do not intend to confine the invention to this or to any other specific form of bearing rings and rollers. Loosely mounted on the tie-rods d are the spac ing-rollers e, of a lesser diameter than the bearing-rollers c and contacting therewith to hold the bearing-rollers properly spaced during their combined revolution with the beardiate the ends,upon which are loosely mounted the spacing-rollers e, the spacing-rollers contacting only with the journals.

As shown in Fig. 3 of the drawings, the shanks ot' the tie-rods are screw-threaded and pass through corresponding apertures g in the bearing-rings, the shanks d being fitted on the outer side of the bearing-rings with nuts h to prevent the outward displacement of the bearing rings and on the inner side of the bearing-rings with separable washers 2', bearing against the inner faces of the bearing-rings and the shoulders of the journals 6 to enable the tie-rods to hold the bearingrings properly spaced. Said washers are of greater diameters than the journals, while the journals are of greater diameters than the tie-rods.

As shown in Fig. 3, the tie-rod is fitted with a single spacing-roller to contact the adjacent bearing-rollers, the spacing-roller being located intermediate the ends of the tie-rod and of a sufficient length to form a substantial contact with the bearing-rollers and maintain them in their relative alinement, the spacingrollers being prevented from moving longitudinally on the tie-rods by the washers i, abutting against the inner faces of the retainingrings and the shoulders of the tie-rod journals, there being sufficient clearance between the ends of the spacing-rollers and washers to allow of the free revolutionof the spacingrollers on the journal.

In Fig. at I form the tie-rod with the enlarged central portion or journal f, which has mounted thereon the spacing-roller e, which is shorter in length than the journal. In this form I also dispense with the use of one nut, as h, by threading the opening in one of the bearing-rings to receive the'threaded end g of the tie-rod. Upon the tie-rod, between the journal f and the bearing-rings, are the long washers c".

In Fig. 5 each tie-rod is shown to be fitted with two spacing-rollers e, loosely mounted on journals rotated in juxtaposition to the tie-rod shanks, the inward displacement of the spacing-rollers being prevented by shoul dersj on the tie-rods d" and the outward displacement by the Washers i", a sufficient clearance existing between the ends of each spacing-rollerand its respective washer and shoulder to allow of the free revolution of the spacing-roller on its respective journal.

Having thus fully described my invention,

2. In a roller-bearing, the combination of the bearing-rollers, bearing-rings therefor, tie-rods for holding the bearing-rings relatively to the bearing-rollers, there being journals on the tie-rods, spacing-rollers mounted on the journals'and having their outer ends within the ends of the bearing-rollers, and Washers of greater diameters than the journals mounted upon the tie rods to abut the shoulders of the journals and the inner faces of the bearing-rings.

3. In a roller-bearing, the combination of the bearing-rollers, bearing-rings therefor, tie-rods for holding the bearing-rings together, spacing-rollers mounted on the tierods, abutting means for the inner faces of the spacing-rollers, and Washers at the outer ends of the spacing-rollers.
